Given the Following Stack Declaration, Which of the Following Function

Multiple Choice

Given the following stack declaration, which of the following function definitions would correctly push an item onto the stack?
Struct StackFrame
{
Char data;
StackFrame *link;
};
Typedef StackFrame* StackFramePtr;
Class Stack
{
Public:
Stack ) ;
Stackconst Stack& a_stack) ;
~Stack ) ;
Void pushchar the_symbol) ;
Char pop ) ;
Bool empty ) const;
Private:
StackFramePtr top;
};

A) void Stack::pushchar the_symbol)
{
StackFrame temp_ptr;
Temp_ptr = new StackFrame;
Temp_ptr->data = the_symbol;
Temp_ptr->link = top;
Top = temp_ptr;
}
B) void Stack::pushchar the_symbol)
{
StackFramePtr temp_ptr;
Temp_ptr->data = the_symbol;
Temp_ptr->link = top;
Top = temp_ptr;
}
C) void Stack::pushchar the_symbol)
{
StackFramePtr temp_ptr;
Temp_ptr = new StackFrame;
Temp_ptr->data = the_symbol;
Temp_ptr->link = top;
}
D) void Stack::pushchar the_symbol)
{
StackFramePtr temp_ptr;
Temp_ptr = new StackFrame;
Temp_ptr->data = the_symbol;
Temp_ptr->link = top;
Top = temp_ptr;
}
